zen of the United States, residing at St.`

Louis, Missouri, have invented a certain 5 new and useful ImprovementinTabulat-ing Mechanism for Type-I/Vriting Machines, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specieation, in which- Figure l is a fragmentary frontfelevationalview showing my improved column stop lr tabulating mechanism fortypewrit- .ichines Fig. 2 is a side elevational is a top plan view. Fig.4: is a detail edge view of one of the column stops. Fig. 51s

This invention relates to tabulating mechanism for typewriting and othermachines, and particularly to column stops thereof.

The object is to provide simple and inexpensive means for enabling themachine to be set for different kinds of tabulat-ing work.

In carrying out my invention, there is -a series of column stops, ,eachof which is movable ina plane transverse to the rod in which it ismounted into and out of position with respect to the, carriage or rackwith which it coperates. These stops are independently` adjustable alongthe rack. and each is: provided with means for holding it into and outof its effective position.4

In t.he, drawings, l indicates the denomination ke s mounted upon levers2, these keys heini depressed to lift the rods `3 Vforn1ed withdenomination stops 4 at their upper ends. These denomination stops arepreferably out away at one side or have their uppergends beveled, asAshown in Fig. 4, so that whemthey are raised into position to cooperatewith the column stop they will arrest said column stop midway a stepor'escapement space, whereby, when said stop fl releases the column stop,said column stop will move! thereover so as to be out of the way of thlebeveled edge of the stop 4, and permit a second operation thereof, andalso whenthe'l carriage is being returned to its home position, t-hestop 4, if it should accidentally be left elevated, will `be presseddown to its lowered position.

Each rod 3 is provided with a shoulder 5 to engage a rack plate 6mounted. on the frame ofthe machine, whereby, when the rod 3 is raised.plate 6 will be moved back so as to move the. upper end of shaft 7rearwardly. The upper end ofshaft- 7 carries a pinion 8. which mesheswith a rack 9 on the carriage, and said shaft is preferably mounted in abearing- 10. which is normally held in a' forward position by means of aspring 11. Shaft 17 carries an eseapement wheel 12, which may be of anyusual construction.l The lower end of shaft 7 is mounted in a stepbearing` 13, in which is a slight playLso as to permit the movement ofits upper end.

1i is a ball bearing track on the frame of the machine. with whichcoperates carriage track nieuwer. 15. The front face of this carriage tack member is provided with rack teeth 16.

17 is a rod mounted on the vcarriage adjacent the track member 15, saidrod being preferably flattened on its upper face and carrying a scaleindicating the space members. Y A' j 1S is a column stop having its rearedge provided with teeth 19 to coperate with the rack teeth 16. Thelower edge of this column stop is provided with a beveled projection Q()for cooperating with the stop plate 4.

21 is a handle ar 'anged in the column stop and preferably made hollowso as t-o contain a spring 29., which .A normally operates through afollower 22 upon the fiat face of the. rod 17 to hold the stop inoperative position.- When it is desired to adjust the stoplongitudinally on the rod 17, the stopV is rocked on the shaft-17 sothat the teeth'lt) are moved in a direction transverse the rack 16 andout of engagement t.herewit-h, where by the said stop may be adjust-edlongitudi- -nally on the shaft.

Vhen adjusted to its proper-position, the stop is again rocked on theshaft so as to engage its teeth 19 with the rack. j

I claim:

l. In a tabulating mechanism, the combination of a rod having aflattened portion, column stops mounted to slide upon and oscillateabout said rod, said stops comprlsmg a projecting beveled faced member,and a handle member having a spring-pressed follower mounted therein,adapted to engage the flat portion ofthe shaft to retain the stops inposition.

2. In a tabulating mechanism, the combination of a rod, a column stoprotatably and slidably mounted upon said rod, and a denominational stop,said column stop being provided with a stop face, a portion of said stopface lying intermediate said denominational stop and Said rod.

3. In a tabulating mechanism, the combination of a carriage and a racksupported thereby, a rod extending along said rack, a column. stopmounted upon said. rod in such manner as to be capable of beingoscillated around and slid upon said rod, said column stop beingprovided with a stop face, a machine yframe upon Which said carriage ismounted, and a stop carried by the machine `frame, the construction andarrangement of parts being suchh that a portion ofthe stop face of thecarriage stop is between a portion of said rod and said stop on themachine frame in such manner that pressure exerted on said column stopby means of said stop carried by the machine frame will be delivereddirectly upon said rod.`

4. In a tabulating mechanism, the combination of a rod, a column stoprotatably and slidably mounted upon said rod, a key operated stop, astop tace upon said column stop, said stop face extending between saidrod and said key operated stop and at right angles to the movement ofsaid key operated stop.

5. In a tabulating mechanism, the combination of a rod, a column stoprotatably and slidably mounted upon said rod, a key operated stop, astop face upon said column stop, said. stop face extending between saidrod and said key operated stop, and a key for moving said key operatedstop in a direction substantially at right angles to /said stop face.
